On an admittedly rapid read through those texts (RFC3315, RFC5969, the above draft) all references to subnet router anycast addresses were inside "SHOULD" clauses. Which implies that there are alternative methods of achieving those aims? One alternative would be to make the subnet router anycast address well-known rather than reserved. Then it could be used in environments that need it, and would not interfere in environments that do not.
